What's the difference between MOBI and TXT?
MOBI (Mobipocket ebook) and TXT (Plain text) solve different problems: MOBI is a ebook format format built for older Kindle devices and legacy ebook libraries, while TXT is a document format format whose strength is notes, logs, data exchange, feeding text to other tools. In practice you will meet MOBI when dealing with older Kindle devices and legacy ebook libraries, and reach for TXT when you need notes, logs, data exchange, feeding text to other tools — the table below compares them point by point.
| MOBI | TXT | |
|---|---|---|
| Full name | Mobipocket ebook | Plain text |
| Developed by | Mobipocket / Amazon | — |
| Released | 2000 | 1963 (ASCII) |
| Compression | Ebook format | Document format |
| Typical use | older Kindle devices and legacy ebook libraries | notes, logs, data exchange, feeding text to other tools |
| File extension | .mobi | .txt |
| MIME type | application/x-mobipocket-ebook | text/plain |
Why convert MOBI to TXT?
MOBI is the ebook format created by French company Mobipocket in 2000 and acquired by Amazon in 2005, where it became the foundation of early Kindle books. It stores reflowable text in a PalmDB container. Amazon retired MOBI support for Send to Kindle in 2022 in favor of EPUB, so today MOBI mostly appears in older ebook collections. Here is when TXT is the better choice:
- →TXT opens everywhere, forever — no reader app, no compatibility questions, no format rot.
- →Extracting a book or document to plain text is ideal for search, scripts, translation tools, and AI workflows.
- →It runs in the cloud — 10 free conversions a day with files up to 200 MB (20/day and 500 MB with a free account) — so even a phone or an old laptop converts at full speed.
Before you convert: three quick tips
- ●Make sure the file is DRM-free — DRM-protected ebooks (e.g. books bought from the Kindle store) cannot be processed by any conversion tool, for both technical and legal reasons.
- ●Sending to a Kindle? Pick AZW3 for USB sideloading (any Kindle since 2011), or send an EPUB through Send to Kindle (supported since 2022).
- ●Keep your original MOBI — conversion never modifies it, and if you later need a different target format, starting from the original always gives the best quality.
TXT conversion settings explained
Ebook conversion runs on Calibre's ebook-convert engine with no settings to tune: chapter structure, table of contents, metadata (title/author), and embedded images migrate to the target format automatically.
PDF output uses A4 pages with comfortable margins; PDF input enables line-unwrapping heuristics that reconstruct continuous paragraphs wherever possible.
How the conversion works
Filevo's MOBI to TXT conversion is powered by Calibre's ebook-convert engine — Calibre has been the de-facto standard of ebook management for two decades, its conversion pipeline trusted by millions of readers and libraries. It parses the source into a unified intermediate structure and regenerates the target format from it, explicitly carrying chapters, table of contents, and metadata through the pipeline. The conversion runs in the cloud — no Calibre install needed on your device.

What is TXT?
TXT is plain, unformatted text — the simplest and most durable file format in computing, readable on literally every device ever made. It carries no fonts, images, or layout, just characters. That makes it tiny, future-proof, and the format of choice when only the words matter.

MOBI to TXT converter FAQ
How do I convert MOBI to TXT for free?
Drop your MOBI file into the converter at the top of this page, confirm TXT as the target, click Convert, and download the result. It is genuinely free: 10 free conversions a day with files up to 200 MB (20/day and 500 MB with a free account), no watermarks, no software to install, no account required.
Is it safe to convert MOBI files online?
Yes. Transfers are TLS-encrypted end to end, and conversion is fully automated — no human ever sees your files. Your uploaded MOBI is deleted the moment conversion finishes, and the converted TXT auto-deletes after 24 hours (you can delete it sooner). We never use your files for AI training or share them with anyone.
Will I lose quality converting MOBI to TXT?
Converting to plain text extracts all textual content and, by definition, discards formatting: fonts, bold, images, and table layout do not survive — that is the whole point of TXT. The words themselves carry over completely.
How long does MOBI to TXT conversion take?
Usually seconds. The conversion itself takes from under a second to a few seconds for images and audio — most of the wait is the upload, which depends on your connection speed. Since processing happens in the cloud, your device stays fast, and you can run several conversions in parallel.
Can I convert MOBI to TXT on iPhone or Android?
Yes. Filevo runs entirely in the browser, so it works the same on iPhone, Android, tablets, and computers — no app to install. On mobile, tap Browse Files to pick from your photos or files.
What's the maximum file size?
Anonymous conversions accept files up to 200 MB; a free account raises that to 500 MB. Paid plans go from 1 GB up to 10 GB per file, with higher daily limits and priority queues.
Can I convert multiple files at once?
Yes. Drop up to 50 files at once — they roll through the queue automatically. Pick a target format per file or set one per category, then download results individually or grab everything as a single ZIP.
What will the converted file be named?
Your original name is kept and only the extension changes — holiday.mobi becomes holiday.txt, so files stay easy to find.
Whether you need notes, logs, data exchange, feeding text to other tools or simply a file that works where MOBI will not open, the converter above turns MOBI into TXT in seconds — free, private, and with nothing to install. Bookmark this page for the next time a MOBI file refuses to cooperate.
